Lines in LCD tv moving from bottom to top when connectin RCA
The problem is this, if i connect an AV cable (rca) directly from the cable tv box to the tv (video 2) lines can be seen and is very annoying, but if i connect only the coaxial cable that comes from the outside om my home directly to the tv there's no line.
Re: Lines in LCD tv moving from bottom to top when...
There may be a ground loop in your electrical wiring. Try connecting a 3 prong to 2 prong AC adapter between the power cord and the electrical wall outlet. You can find one in any hardware store for around one dollar. This will lift the ground from the TV. If your lines go away you may have an issue with your electrical wiring in the house or on an internal part on one of the components. The least expensive fix is to leave the adapter in place. I hope this helps.

I am assuming this should read 'Set top box'. What kind of cable are you using?
Usually the set top box connects via a SCART lead but yours may be HDMI if it is a very new set top box.
If you are using RCA plugs, you may have cross connected the wrong cables. The RCA cables should be colour-coded. RED and WHITE are for audio, Yellow is for video.
Best advice is to switch it all off, remove all the cables you attached, and start again. The instruction manual/user guide usually has an illustration to help you identify what your set up looks like - there are usually several examples.
If the cables you need did not come with the set top box, you will need to purchase them.
When you are connecting audio leads, you should use the 'audio out' on the set top box and the 'audio in' on your TV set.
It would help to know the EXACT model number of LG screen you have and the make and EXACT model number of the set top box.
Easy. All you have to do is to make sure that the DVD player is old the older types that have RCA connectors at the back of the DVD. Latest DVD may have RCA connections but I am not sure if it can send digital signal directly to the analog TV. Try this and see what happens. if your TV is old and does not have Component Video (Red/Green/Blue) RCA sockets (input) but has standard Pal/NTSC sockets (Yellow/Red/Black) hook up the yellow, red and black plugs into a DVD (out) RCA sockets of same colour, then hook up the other end of the cable in the (in) RCA sockets at the rear of the TV.
If it works, then all is well. If it doesn't work, then you have to hook up the cable from the DVD to the (input) RCA sockets of a Set Top Box, so that the Set Top Box will convert the signals for the analog TV. Just pay attention to the inputs and outputs at the rear of them.
On your DVD - plug the RCA cable to the (OUTPUT) RCA sockets. On the Set Top Box - plug the connectors in the (IN) RCA sockets and then use another cable connected to the OUT RCA's of the Set Top Box, then connect the other connectors to the (IN) of the TV RCA sockets. Hopefully you get the picture on what I mean.
Hi, Your set top box (PVR) is running on channel 3 or 4. Go to menu and sellect a source TV, DVD
Note: Do not connect more than 1 set of cables to tv or you may damage something.
TV > box connect RCA cable or HDMI not both.
Set top box > connect RCA or HDMI Not both.
audio devices > TV connect RCA or HDMI not both.
Component will give you the highest quality signal (as long has the cable box supports this connection) You will also need to connect the Audio connectors (red/white RCA) from the cable box to the TV as well.
This kind of tv u must have cable or satalite tvs pay broadcasting signal cable,so u have a box .Tv have HDMI ports or RCA AV component cable input?The incomming broadcating tv signal go to the cable or satalite boxes.Than u use a HDMI cable or RCA AV component cable go through those boxes than to ur tv HDMI input ports or RCA AV component cable input holes.
Your TV is a High-Def TV (HDTV) therefore you need a Rogers cable box and service capable of High-Definition in order to get the HD resolution you paid for with the HDTV. HD video requires HDMI or component video cable connections. Standard RCA AV (yellow, white, red) will not show HD video.
Having said that, you may want to hookup a game or VCR to the TV and therefore you will need to get a cable known as an AV miniplug. It has RCA (3) on one end for the VCR for example and on the other end is a Mini-plug to connect to the HDTV (Sharp). This cable is like the ones used on camcorders such as Sony. Make sure you get a cable with the right ends as depicted in your manual on page 14.
You'll have to Google online for a supplier. Sparco.com had these cables but are out of stock currently.
If u plan to just to watches video only,than just used a RCA AV component RYW connections hook directly to the LCD tv is find.But if plan to record shows and things to the VCR tapes,than the VCR unit must hook through to the cable box.
WHAT HAPPENS WHEN YOU USE A DVD INPUT (AV) OR A SAT/CABLE BOX CONNECTED TO THE AV INPUT'S ,,IF IT CLEARS UP YOU HAVE A SIGNAL BOARD BAD BUUUUUUT YOU CAN BYPASS THAT BOARD AND SAVE MONEY JUST BY USING THE AV INPUT...TUNICA
Connect the AV output of the Sky box to the AV input of the Panasonic combo.Look at rear of the Combo and you will observe input and output RCA connections.Using RCA leads, hookup the Av output of the Panasonic to the audio/video input of the Sony tv. Power up Appliances, and you should be OK.
Make sure that you have connected the cable box properly to the TV.
Use the audio and video OUT from the box to the TV IN.
Select the correct input on the TV.
Connect it using any of the following: A HDMI cable (1 cable for both audio and video), Component Cables (3 RCA's red, green, blue) + RCA audio cables (1 for mono or 2 for stereo), S-Video + RCA audio cables (1 for mono or 2 for stereo), or AV cables - 1 RCA for video (usually marked yellow) + RCA audio cables (1 for mono or 2 for stereo).
